TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 619,260, dated February*7, 1899.

Application filed June 6, 1898. Serial No. 682,716. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM P. QUIMBY, residing at Gettysburg, in thecounty of Adams and State of Pennsylvania, have made certain new anduseful Improvements in Type-\Vriters, of which the following is a full,clear, and exact description.

My invention is an improvement in typewriters, relates particularly tothe spacing mechanism, and has for an object to provide a simple novelmechanism whereby a single or double spacing may be effected by onemovement in order that an operator in printing the last letter of a wordmay simultaneously with such printing movement effect a double spacingto provide for the usual spacing between words.

My invention involves certain improvements in the escapement mechanism,as well as in the intermediate devices between the same and the type andspacinglevers; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described,and pointed out in the claims.

In the drawings, Figure 1 is a perspective View illustrating myimprovements, parts of the machine being removed and others shown insection. Figs. 2 and 3 are detail perspective views showing theescapement-wheel and the parts immediately connected therewith. Fig. 4is a perspective view similar to Fig. 3, showing the escapement-lever ina different position. Fig. 5 is a detail vertical section on about line5 5 of Fig. 4. Fig. 6 is a detail view illustrating the movable stop forthe loose dog of the escapement. Fig. 7 is a detail perspective viewillustrating such stop as raised out of the path of the baseplate of theloose dog. Fig. 8 is a detail plan view illustrating the slidingescapement-plate with the loose dog and the stops therefor in position.Fig. 9 is a perspective View illustrating a somewhat different mechanismintermediate the keys, and the step-bystep spacing mechanism.

In carrying out my invention the typewriter frame, its type-levers A,spacing-lever B, carriage G, with rack C, and the escapement-wheel D mayin general respects be of the usual construction.

In connection with the escapement-wheel D I provide a fixed dog E and aloose deg F to secure the desired feed of the carriage for spacing, andin securing such spacing I provide for a variable movement laterally ofthe loose dog F, so such dog may when released from the escapement-wheelmove laterally a distance equal to one tooth of the wheel or equal totwo of such teeth, as may be desired. In effecting such result I providethe rocking escapement-lever G with a plate H, which slides back andforth on the top plate H of the machine-frame and supports the rigid dogE and the loose dog F; and I provide mechanism, as will be presentlydescribed, whereby the movement of the lever G may be sufficient topermit the escapement-wheel to move one step or two steps,as may bedesired. While Irefer to the tooth E as rigid, it should be understoodthat I prefer to make such tooth rigid in operation, and yet provide, bymeans of the slot E and the screw E for adjusting the dog E on the plateH to take up wear or for any other purpose desired. The loose deg F ismovable laterally on the plate H, being provided with a base-plate F,sliding on such plate II and guided in keepers F This plate F is pressedlaterally by thespringI into contact with a stop J or a stop K when suchstop J is lifted. This stop J is movable and is arranged in position tostop the loose dog F in position to secure a single spacing of thecarriage, while the stop K is in position to stop the said dog inposition for a double spacing of the carriage if the stop J be raised sothe dog can move on into contact with the stop K. The stop J is down inposition to be engaged by the base-plate F at all times when the rockinglever G is given the slight movement necessary to secure a singlespacing of the carriage; but if the rocking lever G be given the extentof motion necessary to effect a double spacing, the stop J will be movedout of the path of the plate F and the latter may move into contact withthe stop K. This is preferably effected by pivoting the stop J at J andproviding it with an arm J which is pressed upon by a spring J 3 in suchmanner as to hold the stop J normally in the path of the plate F and yetpermit it to rise out of the path of such plate, so the plate F can moveon into contact with the stop K. This movement of the stop J out of thepath of the plate F is preferably secured by providing at L a devicewhich will engage the arm J 2 of the stop J when the plate H is thrownforward sufficiently far to effect a double spacing of the carriage.screw, as shown in Figs. 5, 6, and 7, and can be readily adjusted tosecure the desired operation of the stop J, as will be understood fromsaid figures.

In operation the dogs E and F act in coning controlled by the movementsof the rocking esoapement-lever, the usual movement thereof moving theplate H but a short distance, so the arm J 2 will not strike the stop L,while a greater movement of the rocking lever will cause the arm J 2 tostrike the stop L, so the plate F can pass on into engagement with thestop K, and thus provide for a double spacing of the carriage. In orderto provide for this variable movement of the lever G, I pivot thereto aconnecting-lever M, such lever being pivoted at M centrally between itsends to the lever G, and the framing being provided with abutments N andO, which serve as stops to limit the upward movement of theconnecting-lever M and also as fulcra for the opposite ends of .suchlever as the same is depressed'at one or the other end in the operationof the machine.

by the spacing-lever and the keys may act thereon to depress one or theother end of such lever or to move the same bodily downward. As shown inFig. land as may be preferred, shafts 1 and 2 are journaled to theframing and have crank-arms 3 and 4, connected by links 5 and 6 with theends of lever M and crank-arms 7 and 8, which are operated,respectively, by the spacing-leverB and the type-keys, the spacing-leverB being connected with its crank-arm 7 by a link 9, and the keys, ofwhich I show only one, being arranged to engage the lower cross-bar 10of .a bail, whose end rods 11 connect with the cranks of the shaft 2.The spacing-lever B is cut out at B, where it crosses the bar 10. It ismanifest that the keys or the spacinglever when depressed will rocktheir respective shafts 1 and 2 and depress the corresponding end of thelever M, operating the lever G sufficiently to secure a single-spacingmovement of the carriage, but if the typekey and the spacing-lever beoperated at the same time the bar M will be moved bodily downward (seeFig. 4) and efiect a sufficient movement of the lever G to secure adoublespacing movement of the carriage.

It will be noted that the extent of movement of the key and spacinglevers is the This stop is preferably a' For operating the lever M, Iprovide means wheresame both when the levers are moved alone and whenthey are moved jointly.

In Fig. 9 I show a different construction between the type-levers andthe spacing-lever and the lever M, to which, at its opposite ends, areconnected the upper cross-bars P and Q of bails Q and P, the lowercross-bars Q and P of which are arranged, respectively, for engagementby the spacing-lever B and the type-lever A, so such levers may whendepressed move downward their respective bails to rock theconnecting-lever M, as indicated in Fig. 3. While the levers A and Bcross both bars Q and P I prevent the operation of the bar Q by thelever A and the bar P by the lever B by providing said levers A and Bwith cut-out portions A and B, corresponding to the cross-bars whichthey cross, but are not desired to operate, as will be understood fromFig. 9. In the operation of such construction if the type-levers A, ofwhich I show only one, are depressed they will push down the bail P andthe crossbar P will tilt the lever M by causing one end of such lever tofulcrum against the stop N, and the reverse result will occur when thespacing-lever B is operated, such lever depressing the bail Q andtilting the lever M to the position shown in Fig. 3. Either of suchoperations serves to rock the lever G the distance necessary to efiect asingle spacing movement of the carriage, the extent of movement of thelever M and the lever G being indicated in Fig. 3. Now if it is desiredto move the lever G a distance sufficient to efiect a double spacingas,for instance, in printing the final letter of a wordthe operator instriking such letter will at the same time strike the spacing-lever. Bythis operation both bails P and Q are depressed, and the lever M,instead of being depressed at only one end, is depressed at both endsand moved bodily downward, thus rocking the escapement-lever G to agreater extent than before and giving to the plate II sufficientmovement to cause the arm J 2 to engage the stop L and lift the stop Jso the loose dog F can move a sufficient distance to secure adouble-spacing movement of the carriage. It is manifest that by thisconstruction the operator is able to save one movement for each wordwritten, as the same movement which prints the final letter of a wordalso operates to secure the spacing between such word and the next.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-
